2. Disconnect the connectors from each solenoid valve.
3. Measure the resistance between contacts 1 and 2 of the connector of each solenoid valve (Fig. 13.24).
Fig. 13.24. Measuring the resistance of the electromagnetic valve
Resistance of all electromagnetic valves at 20°C: 2.7-3.4 Ohm
4. If the valve resistance differs from the required value, replace the solenoid valve (Fig. 13.25).
